An advocacy group that examines an issue from a singular point-of-view risks alienating those facing similar issues yet hold other perspectives, thus shutting down dialogue. It becomes a power struggle, rather than finding solutions through commonalities and balancing conflicting interests. This is not to say that non-confrontational approaches are perfect, but they provide a much more solid foundation for negotiation.
